Adventure seekers from overseas have signed up for the Bermuda Triple Challenge, as registration opens to entrants from around the world as well as around the Island.

The charity event, billed as Bermuda’s only obstacle challenge, has blossomed into a sports tourism event.

Alaska adventure athletes Matt and Tiffanie Novakovich, a Spartan Race-sponsored husband and wife team from Anchorage, are confirmed as taking part, along with Juliana Sproles, of California, the 2011 female champion of the World’s Toughest Mudder endurance course.

Describing it as a “win-win”, co-founder Reid Robinson said the challenge brought people together and inspired teamwork while raising funds for youth charities, which help to marshal the events.

“Many Bermudian charities are struggling and including more adventure seekers from outside Bermuda will help increase efforts to raise money for our local charities,” he said.

The challenge commences on Friday, March 13, with the Argus Urban Foot Race through the streets of St George’s.

That 7pm event closes with a community block party with DJ, bouncy castle and a bucking bull.

The Triple Challenge resumes at 9.30am on March 14 on South Shore for the KRyS Global Island Challenge, and at the same time on March 15 with what organisers called “an all-out assault on the Royal Naval Dockyard” with the the ACE Group Royal Challenge. The last event closes with a participants’ appreciation brunch.

Teams of two or four have to run, jump, crawl and climb their way to the finish, but can also supplement their physical prowess with fundraising power, as they compete for the $1,000 cash prize.

To sign up for any or all of the challenges, register at the site www.racedayworld.com, or see www.bdatriplechallenge.com for more information about the event.

This year’s charities are the Sunshine League, Knowledge Quest, Raleigh International, the New Beginnings Education Trust, Somerset Primary PTA and Big Brothers, Big Sisters.

Sponsors are KRyS Global, the ACE Group, the Argus Group, Butterfield & Vallis and the Bermuda Tourism Authority.
